FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 503,763, dated August 22, 1893.

Application filed February 24, 1893. Serial No. 463,554. (No model!) .To aZZ whom t may concern:

Be it known that I, MARVIN M. FENNER, a

citizen of the United States, residing at Waupun, in the county of Dodge and State of Wisconsin, have invented a new and useful Fountain-Pen, of which the following is a specilication.

This invention relates to fountain pens; and it has for its object to provide certain improvements in pens of this character, to secure efficient means whereby the ow of the ink shall be accurately regulated, while at the same time overflow and other disadvantages of and objections to ordinary fountain pens will be avoided.

To this end the main and primary object of the invention is to provide improved feeding and penholding devices.

With these and many other objects in view which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawingsz-Figure l is a perspective view of a fountain pen constructed in accordance with my invention. Fig. 2 is a central longitudinal lsectional view of the pen enlarged. Fig. 3 is an enlarged detail in perspective of the feed plug with the detachable nozzle. Fig. 4 is a similar View of the feed plug with the pen removed, and

separated from the nozzle. Fig. 5 Ais an enlarged transverse sectional view on the line mof Fig. 2. l Fig. 6 is a detail in perspective of the independent auxiliary feed conductor or reed.

Referring to the accompanying drawings, A designatesthe main part or barrel of theV pen, which,'as is usual in fountain pens, is made hollow and forms the ink receptacle or reservoir. ed at its open end as at a, to detachably receive the threaded end of the detachable nozzle C. The detachable nozzlerC, has an interiorly tapered bore D, which isadrapted to receive the exteriorly tapered cylindrical feedplug E, which is adapted to have a wedrging fit inside of the detachable nozzle C, sofas to.

The barrel A, is interiorly threadform an ink-tight joint, while at the same time being capable of separation from the nozzle with slight force. The cylindrical feed plug E, is open at its inner` end communicating with the interior of the ink reservoir or barrel A, while from the other end thereof extend the reduced upper and lower feed tongues F and F', respectively. The upper and lower feed tongues F and F, are separated from each other and are formed by the longitudinal combined feed and pen-point slit G. The slit G, extends from between the outer extremities of the feed tongues F, and F', a sufficient distance into the closed ends Vof the feed plug, so as to accommodate nearly the entire length of the pen point H, which is adapted to be inserted into said slit between said feed tongues. The tongues embrace the upper and lower sides of the pen point and extend near to the writing extremity of such point, so as to not only rmly hold the pen point in position, but also to insure a double feed of ink thereto from the top and bottom sides thereof. As clearly shown in the drawings, the slit G, is curved so as to correspond to the curvature of the pen point which snugly registers in the slit. The innerfaces of the upperandlower equal length feed tongues F and F, which contact with the upper and lower sides of the pen point, and a portion of the feed plug itself which embraces the pen point, are provided with the longitudinally disposed ink grooves or channels I, which serve as capillary passages for the feed of the ink from the main part of the feed-plug to the upper and lower sides of the pen point, as will be readily apparent. By reason of having the upper and lower feed for the pen point, the amount of ink required for writing can be accurately regulated, the amount or quantity of ink iowing, depending upon the pressure on the pen point, so that the operator can make a heavy or light stroke at his option, it being apparent that with the double feed he can make a heavier stroke than could be made with a pen hav- `ing a single feed,owing to the fact that more ink can be supplied quicker t0 the point.

In order to secure the proper regulation and feed ofthe ink to the upper and lower portions of the lpen point, I employ a vregulatin g ball-valveJ. The said ball valve J, is arranged inside of the cylindrical feed plug, E, and is slightly smaller in diameter than the same so'as to rest on top of the inner endof the pen point. The `saidball .valveVbyl` resting on the inner end of the 'pen point, keeps the pressure, due to the weight of the ink in the barrel or reservoir, oof the .p en,.;. but when the pen is in use, its motion gives motion to the ball., so as to work the ink` by" the same, and vdto-feed thepen p ointjas quicklyg or as slowly as the rapidityof ,pressuregof the;E Writing requires. The ball lvalve steadies" the flow of ink irrespective of the amount offl ink inthe barrel. v

To provide for the-auxiliaryfeeding ofthe .ink from -th'e tbarrel -into the l.feed plug-and -vice versa, 1 employ a separate :and inde-* pendent :flat conductor-reed .'K. llheliia'tcon--v ductor `reed K, is of al width allow-ingitslwedgr` ing insertion intoithe inner open -endof 4the.
